Doped Fiber Pump Combiner(N+1)x1

Doped Fiber Pump Combiner,also call active pump combiner, is build by coupling pump fiber power directly into doped fiber(say Yb-doped, or Er/Yb doped ect), the signal input fiber is passive fiber, and the splice point is put inside combiner. Normally customer splices doped fiber with combiner output passive fiber, which will cause backward scattering.

Active combiner makes customer no need to splice again outside combiner and will get very good isolation between backward light and pump lasers. The structure has 2 advantages compare with normal combiner:

  • Customer only need splice one time with doped fiber at combiner signal side.
  • The coupling region is behind splice point, the isolation(backward signal to pump) is much lower than normal passive combiner, so that protect pump LD burning.
